Aquarium UV light Sterilizer Water Clarifier UV Light Clean Green Algae Pet Dog House Bacteria-Killer UV Sterilizer Lamp for Sump Filter Tank Pond Swim Pool Home Sterilization (7W 10inch in length)

This product is amazing!!! My tank is a 90 litre marine tank and I’ve been suffering soooo bad with algae blooms for the last month. Did some research and figured I needed one of these, but all costed a lot of money. You couldn’t even see my fish or the back of my tank. So popped it in that night and by the morning the water was completely crystal clear!! Could not believe it. I really really recommend this, it’s been a saviour

I honestly can’t believe this worked as well as it did. I was having issues with bacterial blooms in my 240 litre tank. I tried pretty much every product out there and couldn’t seem to get it under control so I said I would try this. I plugged it in for 2 hours. After just 2 hours my tank is the cleanest it has every been!!! The water is crystal clear and the cloudiness is gone completely. I am so impressed with this product!

Bought last November and no longer works. Not very good.Update.Seller has just been in contact and is happy to replace the UV lamp.Very pleased as a lot of sellers aren't bothered.Great to see and would buy from again.Thank you Sarah.

Waste of £20 turned up today plugged it in, there’s output voltage but lamp is defective.

I have a 80l tank ish I think. It was like pea soup we have a lot of natural light and do t use the aquarium light to keep the algae down. I could not stop the green. Purine sachets, water changes. Took live plants out. Nothing. Tried this with a 3/4 soft water change. This is after 5 days. It’s clearer than a swimming pool. I did leave it on all night first night and killed 5 fish. My mistake. It’s in the filter housing space but it attracts fish at night like moths so just use it in daylight not dark or use a timer. I haven’t had it on today as the water is so clear but maybe I will use it 1-2 hrs per day but also need to make sure the prawns and snails have something left to eat. Yes it was cheap it may not last but it does work and I am happy. Very happy.
